Be it ltnown that liften 11a iirinnison 'Connn'r'iy of iortlai l.,ititilnioinaii county, Urogon, have invented certain non' and uselulliniirovenients in Logging-Engines, oli which the following isspeeiiention. l

.ln logging-engines as usually constructed two winding-drums areemployed, one ior the matin or hziuling cable and the other lor the,

trip-line, which is ettnched .at-one end to the hauling/sable, for thepurpose ol dragging it bank into the woods alter s. log hauled to theeng. e. The innin drinn, or the one on .if'nieh the werking estilo iswenn d, should have reat poner and be operated nt i, eoinparativey slowspeed, while the nuxiliai y or 'trip line drum, having -no otherlunetion than that oi'" dragging the hanlingwahle linut: into the woods,hws power, hut. should he capable of l'iigh speed to insurithe quiet;return of' the linnlingnil le nud 'l'aoilitate the drnwing in oi thelogs. lt. is undesirable in obtaining the de." rat io ol' speed betweenthe mein end e to. usen veri," large genr on. tlnzine..l t drinn with asniall barrelv on ol the enhle, it np the auxiliary drum to the t orhauling ont thel trip-line and z de n drnin ot snilieient eepneity to tnf the trip-line, which e' vionsly iii-.ust he `4man ilo the length olthe, hauling-cable.

For the puriose l obtaining the desired of speed hetween the two druniswithe out increasing their dinnieter to an oltieetionthle degree varioussystems ol' eonipnnnd have been devised, which have generally beeneffet-,tive ns hir as regulating the speed of the drnnis is eoin'erued,lint have beenobjeetional)le on aeeonnt ot' the drunis operating inopposite direi-'ions and eoiling at least one ottheoablestroni theunderside--Y n method whieli in nn appuiratus ot' this hind is veryundesirable, as it necessitates tht` raising ol the drum in the trnine,causing a tendweakness, and iu ense 0l zt shit-.lt line nllows the cabletojdrag on other parts oll the inaohine. 'l`he gipsy head or winehemployed l'or supplenientary work should be mounted to overwiud itseoinparntiwi)Y small cable and he operated rapidly. 'llnIl overwindingoll the line vhas heen obtained by i inunting the wint-,h on the shattot the innin drum l; but the sneed .ot this shaft is too slow vl'or thework o the wine-h and hns nn excess oi' poner.

has heen i i i l l l i l i i i i l The objects, therefore, ot' myinvention are to provide n logging-engine having main and auxiliarydrums between which the desired ratio ol speed is obtained. withoutrunning into very large di nineters.

A ll'urther object is to provide drums operating in the saniedireetionand permitting their eahles to be wound over instead of under theni andthe gipsy-wineh to be located on the high-speed-dru1n Shaft.

A further ohjeet is to place the drums as low its possible .in thetraine, making the appli ent ion ol lall strains direet and overcomingthe ohjeetionable leatnres ot' the ordinary niethod ol eonipound gearingwithout increasing the eost ol' construction.

'.llhe invention consists generally in various,

:constructions and combinations, Lall as hereinafter' described, andparticularly pointed ont in 'the elainis.

ln the aeeonii'ianying drawings, lorining part ol" this speeitieation,Figure l is a pla-n view ot a logging-engine, the niain and auxiliar)rdrums embodying niy invention being illustrated iu horizontal set-tion.Fig. 2 is a seetional `view on the line a' .r ol' Fig. 1., and Fig. l isa side ele\fation. v

ln the drawings, 2 represents a. suitable base or traine whereon n shalt3 is journaled and operated troni the engines 4 in the usual nianner. 5is a pinion keyed on the shaft 3 find meshing with a gear (i, secured ona shalt 7, hnving benriugs S on one side ol' said 'traine and on a bart), extending lengthwise ol' said t`rni-ne,near the niiddle thereol". Aelutehshoe l() ot' suitahle ninteriahsiieh. as woo'd,is seein-ed to thegear and has a wedge-shaped lare to enter a soeket l1, l'ornied on thehead l2 ot n drinn 13, whieh is loosely mounted on said shalt 7 and isadapted to slide into engagei'nent with said eluteh-shoe, but norinallyis held out ol eontaet therewith by a spring lil, eoiled about the saidshalt be-- .iti ol'- gear G thereon. Allange in is provided on the headi7 at the opposite end ot' the drinn to reeeive a bi-alui-strap it),eonnerted with a shatt 2t), that `is roeked by a. lreadle 2l, loentedwithin eonvenient rezu'h olv the operator. 'lhe druni is movedlengthwise 'on the shnl't to leek the l`ri t ion-eluteh by rotating aloosely-n1ounted toothed sleeve in engagement with a tixed toothed ringsaid sleeve hein-g operated lby a lever 21 o r other suitable means.

into the woods after a log has heen drawn in, The drum. having directgearing with the Crank-shaft will operate at a high speed, and thelmuling in of the logs will he thereby greatly facilitated. One end ofthe shaft 7 projects heyondthe traine of the nntohine, and a Winch 22,generally called at gipsy,'. is mounted thereon and equipped with. nlight line (not shown) 'for doing supplementary Work around the engine.This heed should revolve rapidly, and. its line should he over- Woundthereon., and hy .mounting it on the Shaft oi the high-speed drum 1 :imable to aocoinplieh both objects. Upon the forwurd end of the berQ'i'roin the high-speed or tripline drum l provide e shaft .23,journnled in heerngson Seid har and on the opposite side of the freine:ind` Carrying on internal gear-ring 24, secured thereon. The shaft 7extends within this geur ond is provided with e pin ion Zfnieshingtherewith and through whirh and Seid internal gear the slietft- 223 .isdriven at a slower speed. than the shett '7 the proper rat-io beingiobtained in the Wellduiown wn-5f'. A olutelvshoe 26 is mountedon seidgeerring, and e drum 27, loosely mounted on the shaft 23, has e head28., provided. with e tnpered tlange 29 to engage the correspondingsurface of the clutch-shoe, heing heid nor molly out of eonteottherewith 'by a spring 14.@ and box 15, corresponding to the partedescribed with reference to the drum 12%.
